Create union integer with members char c, short s, int i and long b. Write a program that inputs the values of type char, short, int, and long and stores the values in union variables of type union integer. Each union variable should be printed as a char, a short, an int and a long. D the values always print correctly? Also create pseodocode or flowchart.
Here is the feedback that I received when I originally turned this in:
I have the following concerns: You need to save your program file with a .c extension. You should declare your union above the main module and then utilize it from within this portion. You have declared the union and then created a function definition prior to entering the main() function.
Here is the original code provided by homework help: Thanks in advance
#include
union myUnion {
char c;
short s;
int i;
long l;
};
void print(myUnion u) {
printf("As a character: %c\n", u.c);
printf("As a short: %hd\n", u.s);
printf("As an int: %d\n", u.i);
printf("As a long: %ld\n\n", u.i);
}
int main() {
myUnion u;
printf("Please enter a character: ");
scanf("%c", &(u.c));
print(u);
printf("Please enter a short: ");
scanf("%hd", &(u.s));
print(u);
printf("Please enter an int: ");
scanf("%d", &(u.i));
print(u);
printf("Please enter a long: ");
scanf("%ld", &(u.l));
print(u);
return 0;
Answer:
The updated program in C is as follows:
#include <stdio.h>
union myUnion{ char c; short s; int i; long l; };
int main(){
union myUnion inputs;
printf("Character: "); scanf("%c", &inputs.c);
printf("Output: %c", inputs.c);
printf("\nShort: "); scanf("%hd", &inputs.s);
printf("Short: %hd", inputs.s);
printf("\nInteger: "); scanf("%d", &inputs.i);
printf("Output: %d", inputs.i);
printf("\nLong: "); scanf("%ld", &inputs.l);
printf("Long: %ld", inputs.l);
return 0;
}
The pseudocode is as follows:
Function union myUnion {
character; short; int; long
}
main() {
myUnion inputs;
Input inputs.c; Print inputs.c
Input inputs.s; Print inputs.s
Input inputs.i; Print inputs.i;
Input inputs.l; Print inputs.l
}
Explanation:
This defines the union function
union myUnion{ char c; short s; int i; long l; };
The main begins here
int main(){
This calls the union function to main
union myUnion inputs;
This prompts and gets input for character variable
printf("Character: "); scanf("%c", &inputs.c);
This prints the character input
printf("Output: %c", inputs.c);
This prompts and gets input for short variable
printf("\nShort: "); scanf("%hd", &inputs.s);
This prints the short input
printf("Short: %hd", inputs.s);
This prompts and gets input for integer variable
printf("\nInteger: "); scanf("%d", &inputs.i);
This prints the integer input
printf("Output: %d", inputs.i);
This prompts and gets input for long variable
printf("\nLong: "); scanf("%ld", &inputs.l);
This prints the long input
printf("Long: %ld", inputs.l);
return 0;

Explanation:
Suppose you have a stack ADT (i.e., an Abstract Data Type that includes operations to maintain a stack. Design a flowchart or suitable logical diagram to show you could implement a queue’s enqueue and dequeue operations using two stacks, stack 1 and stack 2.
Answer:
One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.
Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).
Dequeueing would be:
- For all items in stack1: pop them from stack1 and push them in stack 2.
- Pop one item from stack2, which will be your dequeue result
- For all items in stack2: pop them from stack2 and push them in stack 1.
Hope it makes sense. I'm sure you can draw a diagram.
Use the tables below to show the difference between the results of a natural join, an equijoin (with PROF_CODE = 2) and a full outer join. Provide the resulting table of each join
Answer:
Code:
CREATE TABLE student (
stu_code INTEGER PRIMARY KEY,
prof_code INTEGER
);
INSERT INTO student VALUES (100278,null);
INSERT INTO student VALUES (128569,2);
INSERT INTO student VALUES (512272,4);
INSERT INTO student VALUES (531235,2);
INSERT INTO student VALUES (531268,null);
INSERT INTO student VALUES (553427,1);
CREATE TABLE professor (
prof_code INTEGER PRIMARY KEY,
dept_code INTEGER
);
INSERT INTO professor VALUES (1,2);
INSERT INTO professor VALUES (2,6);
INSERT INTO professor VALUES (3,6);
INSERT INTO professor VALUES (4,4);
The SQL NATURAL JOIN is a type of EQUI JOIN and is structured in such a way that, columns with the same name of associated tables will appear once only. In our Example, Prof_code will appear only once and it will be matched in both the table;
SELECT * FROM Student natural join Professor on student.prof_code=Professor.prof_code ;
Stud_code Prof_code Dept_code
128569 2 6
512272 4 4
531235 2 6
553427 1 2
EQUI JOIN performs a JOIN against equality or matching column(s) values of the associated tables and an equal sign (=) is used as a comparison operator in the where clause to refer to equality. In our example, it will only show the result with prof_code=2 from the natural join result.
SELECT * FROM Student join Professor on student.prof_code=Professor.prof_code where student.prof_code=2;
Stud_code Prof_code Prof_code Dept_code
128569 2 2 6
531235 2 2 6
In SQL the FULL OUTER JOIN combines the results of both left and right outer joins and returns all (matched or unmatched) rows from the tables on both sides of the join clause.
SELECT * FROM professor full outer join student on professor.prof_code=student.prof_code ;
Stud_code Prof_code Prof_code Dept_code
100278
128569 2 2 6
512272 4 4 4
531235 2 2 6

If you were driving the blue Prius in the situation pictured above, explain why the red Mustang should be given right-of-way at this intersection.
Answer:
The red Mustang should be given the right-of-way at this intersection because:
The red Mustang arrived first before the blue Prius and is closer to the stop sign before the arrival of the blue Prius. This implies that the red Mustang must have waited for its turn, unlike the blue Prius that just arrived at the intersection.
Explanation:
Traffic laws, regulations, and IPDE defensive driving strategy require that drivers always give way to the vehicle that arrived before them at an intersection. Assuming that multiple vehicles reach the intersection simultaneously, then the vehicle must be given the right-of-way. Alternatively, the traffic lights at the intersection should be obeyed and be allowed to regulate the movement of vehicles. IPDE defensive driving strategy requires drivers to be watchful of their driving spaces to determine the appropriate time to move.
Write the code for the following problem.
Add a function to problem to display the last name and highest, last name and lowest and average exam score. Hint: for highest initialize a variable to 0 (high_var). If the array value is higher than the high_var then set high_var to the array value and set high_index to the position of the array. Proceed through the array until you get to the end. Do the same for finding the lowest using low_var set to 999 (higher than the highest value). For the average score, sum all the exam scores as you proceed through the loop. Use a for loop to go through each occurrence of the arrays. Note you can do all this with one for loop but if it makes more sense to you to use multiple for loops that is ok too.

What is hacking? Why is hacking a concern for law enforcement?
Answer:
hacking is the act of exploitation, and is typically used to steal other people's account. It is a major concern because people can easily lose their account to hackers if they're too gullible, and the hacker can use their victims' accounts to purchase the things that they want with their victims' money.
A hammer tool can only be used by one technician at a time to perform hitting. Accordingly, you have developed a Hammer class with a hit method. Objects of class Hammer are used to simulate different hammers, while threads are created to simulate users. Which situation needs to add the synchronized keyword to the hit method
Answer:
Explanation:
The synchronized keyword needs to be active on the hit method at any point where 2 or more threads (users) exists at any given moment. This is in order to prevent two or more users from trying to perform a hammer hit at the same time. This is what the synchronized keyword is used for. It prevents the more than one thread from calling the specific method at the same time. Instead it adds the action to a sequence so that the second thread calls the hit method only after the first thread's hit method finishes.

Of the 4 options, which is the most secured?
WPA was created as a solution to the vulnerabilities in WEP/WEP2. Then, WPA was upgraded to WPA2.
WPA2 is the least vulnerable to hacks because for every user that is connected to the network through WPA2, a unique encryption is made available for such connection.
Hence, the most secure connection, of the 4 is WPA2.
In the context of the components of a typical expert system, _____ is similar to a database, but in addition to storing facts and figures it keeps track of rules and explanations associated with facts.
Answer:
Knowledge base.
Explanation:
Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.
Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.
Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;
I. Non-algorithmic processing.
II. Symbolic processing.
In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.
Hence, expert systems represents knowledge as a set of rules by mimicking the expertise of humans in a particular field to uniquely proffer solutions to a problem.
Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.
Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.
Basically, expert systems comprises five (5) main components and these are;
1. Explanation module.
2. Inference Engine.
3. Knowledge acquisition and learning module.
4. User Interface.
5. Knowledge Base.
In the context of the components that makes up an expert system, knowledge base is similar to a database because it is used for storing facts and figures, while keeping track of rules and explanations associated with facts. Thus, giving rise to the knowledge base management system (KBMS).
In the context of the components of a typical expert system, Knowledge base is similar to a database, but in addition to storing facts and figures, it keeps track of rules and explanations associated with facts.
An expert system is a form of artificial intelligence where computer imitate the decision making style of humans.

A. A "for" loop inside of a "while" loop
B. A "while" loop inside of a "for" loop
C. None of the above
D. Either a or b would work
The type of nested loop which I would use to write the program is:
B. A "while" loop inside of a "for" loopWhat is a Loop?This refers to the control flow statement which is used to iterate and lets a particular line(s) of code execute repeatedly
With this in mind, we can see that the type of nested loop which I would use to write the program is a "while" loop inside of a "for" loop because it is a conditional statement that continues to ask for the certain valid grades until it gets the right one.
